In bowl, combine chocolate, almonds and cinnamon sugar. Gently deflate dough. On floured surface, roll out dough to 12" x 18"; spread with butter. Sprinkle with chocolate mixture. Starting at long end, roll into a log. Pinch to seal. Transfer to parchment-lined cookie sheet. Shape into a ring, pinching ends together. With scissors, make 12 even cuts three-quarters of the way through dough. Cover and let sit 20 min.
